Description

Technical Field

[0001] The embodiments of the present invention relate to the technical field of automatic brake pad processing equipment, specifically, to a fully automatic rotary brake pad processing equipment. Background Technology

[0002] Brake pads, also known as brake discs, are safety components in automotive braking systems that use friction to slow down vehicles. They consist of a steel plate, a heat insulation layer, and friction blocks, and require regular inspection and replacement to ensure safety.

[0003] Traditionally, brake pads were mass-produced, with pre-made blanks processed step-by-step. Key processing steps included grooving, chamfering, and grinding, resulting in the desired brake pad shape. However, with economic development, the number of brake pad (for cars) manufacturers has increased, leading to a proliferation of non-standard brake pads on the market. These designs are largely similar, differing only in the number of grooves, their orientation, and chamfer angles. This has resulted in a wide variety of brake pad types, making it difficult to maintain large-scale production of the same model. Different production equipment or molds are needed for different brake pad models, occupying significant production space. Furthermore, the production requirements for different brake pad models vary, resulting in poor production line compatibility and a high risk of confusion, leading to defective products and further increasing production costs. Therefore, it is necessary to improve and optimize the existing production methods to address these problems. Summary of the Invention

[0004] To overcome the above-mentioned defects, embodiments of the present invention provide a fully automatic rotary brake pad processing equipment, which solves the problems in the related technology that, when faced with the production needs of a wide variety of brake pads, especially when facing multiple models and small-batch production tasks, the traditional old-fashioned single-process processing method is simple, cumbersome and difficult to adjust, has high production costs, low equipment utilization, and cannot meet the requirements of current new products.

[0005] According to one aspect, at least one embodiment of the present invention provides a fully automatic rotary brake pad processing device for processing workpieces, the workpieces having a body portion and metal portions disposed above the body portion and protruding to both sides, including:

[0006] A base frame, wherein a feeding unit, a chamfering unit, a grooving unit and a grinding unit are arranged sequentially and circumferentially;

[0007] A rotating frame is rotatably mounted on the base frame;

[0008] There are several clamping units, which are arranged one-to-one with the feeding unit, the chamfering unit, the grooving unit and the grinding unit. Each of the clamping units is rotatably connected to the rotating frame and is used to clamp the workpiece and rotate circumferentially under the drive of the rotating frame.

[0009] For example, in a fully automatic rotary brake pad processing device provided in at least one embodiment of the present invention, the clamping unit includes:

[0010] A clamping frame is rotatably mounted on the rotating frame;

[0011] There are two clamping components, both of which are slidably mounted on the clamping frame. The two clamping components can slide towards each other to clamp the workpiece.

[0012] For example, in a fully automatic rotary brake pad processing device provided in at least one embodiment of the present invention, the lower end of the clamping frame is provided with a movable part that can extend downward to between the two clamping members, and the movable part is provided with a magnetic suction block for magnetically attracting the workpiece.

[0013] For example, in a fully automatic rotary brake pad processing device provided in at least one embodiment of the present invention, the feeding unit includes:

[0014] A conveyor frame is lifted and mounted on the base frame;

[0015] A conveyor chain plate is circulated and driven on the conveyor frame. The conveyor chain plate includes several hinged conveyor plates and is used to convey workpieces.

[0016] There are two guide rods, both of which extend along the moving direction of the conveyor chain and are slidably mounted above the conveyor chain. The two guide rods can slide towards each other to form a material passage gap for the workpiece to pass through. The end of the guide rod near the workpiece has an arc-shaped chamfer, which is used to guide the workpiece into the material passage gap.

[0017] For example, in a fully automatic rotary brake pad processing device provided in at least one embodiment of the present invention, the discharge end of the feeding unit is provided with a positioning unit. The positioning unit includes a positioning frame mounted at the end of the feeding unit, two positioning support plates slidably disposed on the material receiving side of the positioning frame, and a baffle slidably disposed on the material discharge side of the positioning frame. The two positioning support plates can slide close together to form a positioning groove. The positioning groove and the material passage gap are used to receive the workpiece in the material passage gap. The two positioning support plates are used to support the metal part of the workpiece. A pressure sensor is provided on the positioning frame. The pressure sensor is electrically connected to a controller. An elastic element is connected between the pressure sensor and the baffle. The baffle can press against the elastic element under the action of the workpiece to act on the pressure sensor so that the pressure sensor forms a front-end pressure parameter and transmits the front-end pressure parameter to the controller. The controller is used to generate control commands to send to the feeding unit.

[0018] For example, in a fully automatic rotary brake pad processing device provided in at least one embodiment of the present invention, a side detection component is provided on the positioning support plate. The side detection component includes a side detector, a side trigger rod, and an elastic element II. There are two side detectors, which are correspondingly located on the outer sides of the two positioning support plates. The side detectors are electrically connected to the controller. The side trigger rod is elastically connected to the side detector through the elastic element II. The side trigger rod can press against the elastic element II under the action of the workpiece to act on the side detector so that the side detector forms a side pressure parameter and transmits the side pressure parameter to the controller. The controller is used to generate control commands to send to the clamping unit.

[0019] For example, in a fully automatic rotary brake pad processing device provided by at least one embodiment of the present invention, the chamfering unit includes a chamfering seat that is lifted and mounted on the base frame, a chamfering driver that is mounted on the chamfering seat, and a chamfering disk that is mounted on the output shaft of the chamfering driver. The rotating frame can drive the workpiece to move above the chamfering disk so that the workpiece abuts against the chamfering disk on the raised chamfering seat, and then the workpiece is chamfered by means of the rotating chamfering disk; the number of chamfering units is two and they are circumferentially spaced on the base frame.

[0020] For example, in a fully automatic rotary brake pad processing device provided by at least one embodiment of the present invention, the grooving unit includes a grooving frame that is lifted and mounted on the base frame, a grooving driver that is slidably mounted on the grooving frame, and a grooving disc mounted on the output shaft of the grooving driver. The number of grooving discs is several, and the several grooving discs are spaced apart and arranged in parallel. After the grooving frame rises or falls, it approaches or moves away from the rotating frame. The sliding direction of the grooving frame is perpendicular to the sliding direction of the grooving driver. The rotating frame can drive the clamping unit and the workpiece to move above the grooving disc, so that the workpiece abuts against the grooving disc on the raised grooving frame, and then the workpiece is grooved by means of the rotating grooving disc.

[0021] For example, in a fully automatic rotary brake pad processing device provided by at least one embodiment of the present invention, the number of grinding units is two. The first grinding unit is located between the chamfering unit and the grooving unit, and the second grinding unit is located between the grooving unit and the feeding unit. Each grinding unit includes a grinding frame mounted on a lifting base, a grinding driver mounted on the grinding frame, and a grinding disc mounted on the output shaft of the grinding driver. The rotating frame can drive the clamping unit and the workpiece to move above the grinding disc so that the workpiece abuts against the grinding disc on the raised grinding frame and completes the grinding operation. The first grinding unit is used for rough grinding, and the second grinding unit is used for fine grinding.

[0022] For example, in a fully automatic rotary brake pad processing device provided by at least one embodiment of the present invention, a stabilizing frame is provided on the second grinding unit, and a rotating wheel is provided on the clamping unit. The stabilizing frame has a horizontally extending through groove. The rotating frame can drive the clamping unit and the workpiece to move above the second grinding disc so that the rotating wheel is horizontally aligned with the groove on the raised stabilizing frame. Under the sliding action of the second grinding driver, the rotating wheel can enter the groove to complete the fine grinding process.

[0023] The beneficial effects of the embodiments of the present invention are as follows:

[0024] In this invention, the workpiece is placed on a conveyor chain plate with its steel back facing upwards. The workpiece is positioned between two push rods. With the support of the conveyor plate and the pushing action of the push rods, the workpiece is gradually moved closer to the material passage gap formed by the two guide rods. The workpiece first abuts at the curved chamfer, which guides its forward direction and orientation until it enters the material passage gap. The material passage gap is used to adjust the workpiece's orientation, facilitating clamping by the clamping components and magnetic attraction by the magnetic blocks. The workpiece continues to move along the material passage gap until it reaches below the clamping unit. Then, the conveyor frame rises, at which point the two clamping components are in a distanced state. When the clamping components are at the same height as the steel back of the workpiece, the conveyor frame stops rising, and the two clamping components are positioned on either side of the workpiece. Then, the two clamping components are driven to move towards each other. The clamping elements move closer together until their ends abut against the steel back of the workpiece. At this point, the clamping elements stop sliding, completing the clamping process. Simultaneously, the moving parts extend downwards until the magnetic block abuts against the steel back of the workpiece, completing the magnetic attraction. The magnetic block can use an electromagnet-based method for attraction and separation, or a permanent magnet combined with compressed gas blowing. While attracting the workpiece, the magnetic block ensures the workpiece remains horizontal, preventing skewing. This combination achieves stable clamping of the workpiece and maintains its overall levelness, providing a stable foundation for subsequent chamfering, grooving, and end-face grinding operations, thus improving product consistency.

[0025] The rotating frame is equipped with several clamping units. As the rotating frame rotates gradually, the clamping parts of each clamping unit will clamp a workpiece. Each clamping unit corresponds to a different processing unit. When the rotating frame rotates to a preset angle as required, each clamping unit corresponds to a processing unit. Then the processing unit rises to complete the processing of the workpiece.

[0026] The loading unit is defined as the loading processing position. Around the base frame, chamfering, grooving, and grinding processing positions are arranged in a circle. When the conveyor frame rises, the clamping unit corresponding to the loading processing position begins to clamp the workpiece. The workpieces on the clamping units of the chamfering, grooving, and grinding processing positions are subjected to chamfering, grooving, and grinding operations, respectively. All processing steps are carried out simultaneously, which improves production efficiency. At the same time, the rotating clamping frame can rotate to the corresponding working angle according to the preset operation instructions when processing different types of workpieces, so as to meet the processing needs of stationary workpieces, improve the versatility of the equipment, reduce equipment idle time, and reduce the investment cost of processing equipment.

[0042] Furthermore, in the description of this application, the terms "first," "second," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0043] See Figures 1-8The diagram illustrates a fully automatic rotary brake pad processing device according to an embodiment of the present invention, comprising a base frame 10, a rotating frame 11, and clamping units 70. The base frame 10 is sequentially equipped with a feeding unit 20, a chamfering unit 30, a grooving unit 40, and a grinding unit 50; each of these units can be referred to as a processing unit. Several clamping units 70 are arranged circumferentially on the rotating frame 11. Each clamping unit 70 is used to clamp one workpiece 90. Each clamping unit 70 includes a clamping frame 71 and two clamping elements 72. The clamping frame 71 is rotatably mounted on the rotating frame 11. The two clamping elements 72 are slidably mounted on the clamping frame 71 using a cylinder, as described in the prior art. The sliding directions of the two clamping members 72 are opposite. When the two clamping members 72 approach each other, they can clamp the workpiece 90 for processing, such as chamfering, grooving, and grinding the end face. A telescopic movable part 73 is provided at the lower end of the clamping frame 71. The movable part 73 can be an electric cylinder or pneumatic cylinder with linear drive, as is available in the prior art. A magnetic block 74 is provided at the lower end of the movable part 73. When the clamping member 72 clamps the workpiece 90, the controller on the base frame 10 activates the movable part 73 to extend downwards until the magnetic block 74 abuts against the steel back (metal part) of the workpiece 90. The magnetic block 74 magnetically attracts the metal part of the workpiece 90. The magnetic block 74 and the clamping member 72 work together to clamp the workpiece 90, improving the efficiency of workpiece 90 processing and transfer. To ensure stability and prevent workpiece 90 from falling and causing processing failure, thereby reducing maintenance time and material costs due to workpiece 90 falling off; furthermore, the feeding unit 20 includes a conveyor frame, a conveyor chain plate 21, and a guide rod 22. The conveyor frame is lifted and lowered on the base frame 10 using existing hydraulic cylinders or electric cylinders that can provide linear drive. The conveyor chain plate 21 uses power provided by a servo motor to circulate and transport the workpiece 90 on the conveyor frame. The conveyor chain plate 21 includes several conveyor plates 211 that are hinged in sequence. Several spaced push rods 24 are detachably provided on the conveyor chain plate 21, and each push rod 24 is provided on a conveyor plate 211. The guide rod 22 is provided on the conveyor frame. The guide rod 22 extends along the conveying direction of the workpiece 90. The guide rod 22 can be horizontally slid to adjust the width of the material passage gap 23, thereby adapting to different models of workpiece 90. The workpiece 90 is placed on the conveyor chain plate 21 with the steel back of the workpiece 90 facing upward. The workpiece 90 is located between two push rods 24. With the support of the conveyor plate 211 and the push of the push rods 24, the workpiece 90 is gradually moved closer to the material passage gap 23 formed by the two guide rods 22. The workpiece 90 first abuts at the arc-shaped chamfer. The arc-shaped chamfer guides the forward direction and position orientation of the workpiece 90 until the workpiece 90 enters the material passage gap 23. The material passage gap 23 is used to adjust the placement orientation of the workpiece 90, which is convenient for the clamping of the clamping part 72 and the magnetic attraction of the magnetic block 74.The conveyor frame moves until the workpiece 90 moves along the material passage gap 23 to below the clamping unit 70. Then, the conveyor frame rises, at which point the two clamping members 72 are in a far apart state. When the clamping members 72 are at the same height as the steel back of the workpiece 90, the conveyor frame stops rising, and the two clamping members 72 are located on both sides of the workpiece 90. Then, the two clamping members 72 are driven to move closer to each other until the ends of the two clamping members 72 abut against the steel back of the workpiece 90. At this point, the clamping members 72 stop sliding, completing the clamping process. While the clamping members 72 are sliding, the movable part 73 extends downwards simultaneously until it reaches the magnetic block 74. The magnetic block 74 abuts against the steel back of workpiece 90 and completes magnetic attraction. It can use an electromagnet-based method for attraction and separation, or a permanent magnet combined with compressed gas blowing. While attracting workpiece 90, the magnetic block 74 ensures that workpiece 90 is horizontal, preventing skewing. This combination achieves stable clamping of workpiece 90 and ensures its overall horizontality, providing a stable working foundation for subsequent chamfering, grooving, and end-face grinding operations, thus improving product consistency.

[0044] The rotating frame 11 is provided with several clamping units 70. As the rotating frame 11 rotates gradually, the clamping parts 72 of each clamping unit 70 will clamp a workpiece 90. Each clamping unit 70 corresponds to a different processing unit. When the rotating frame 11 rotates to a preset angle as required, each clamping unit 70 corresponds to a processing unit. Then the processing unit rises to complete the processing of the workpiece 90.

[0045] The loading unit 20 is defined as the loading and processing position. Around the base frame 10, chamfering, grooving, and grinding positions are arranged in a circular pattern. When the conveyor frame rises, the clamping unit 70 corresponding to the loading and processing position begins to clamp the workpiece 90. The workpiece 90 on the clamping unit 70 at the chamfering, grooving, and grinding positions undergoes chamfering, grooving, and grinding operations respectively. All processing steps are performed simultaneously, improving production efficiency. Simultaneously, the rotating clamping frame 71 can rotate to the corresponding working angle according to pre-set operating instructions when processing different types of workpieces 90, meeting the processing requirements of stationary workpieces 90. Figure 8 As shown (excluding some product types), there are many types of workpieces, such as groove types including straight grooves, oblique grooves (single or multiple lines), and horizontal grooves; and chamfered edges of friction blocks, including straight chamfers, inward chamfers, outward chamfers, rhomboid chamfers, asymmetrical rhomboid chamfers, circular chamfers, meridian chamfers, and horizontal chamfers. This improves the overall versatility of the equipment, reduces equipment idleness, and lowers the investment cost of processing equipment.

[0046] In addition, when the clamping member 72 clamps the workpiece 90, both ends of the workpiece 90 abut against the push rod 24 and the baffle 84 respectively. During the descent of the conveyor frame, the workpiece 90 is easily affected by the clamping force of the push rod 24 and the baffle 84, causing a slight tilt. Therefore, the equipment components are optimized. A vertical rod 76 extending vertically is provided at the lower end of the clamping frame 71. The baffle 84 includes a vertical section 841 and an inclined section 842 connected to each other. When the conveyor frame carries the workpiece 90 upward, the lower end of the vertical rod 76... The inclined section 842 abuts against and pushes the baffle 84 to slide away from the workpiece 90 on the positioning frame 81. Finally, the baffle 84 separates from the workpiece 90, canceling the clamping of the workpiece 90. After the conveyor frame stops rising, the two clamping parts 72 approach each other and clamp the workpiece 90. The conveyor frame begins to descend. At this time, the workpiece 90 will not be affected by the clamping of the baffle 84 and the push rod 24, thereby improving the consistency and accuracy of the workpiece 90 clamping state and reducing the risk of incomplete clamping or falling.

[0047] In some examples, see, for instance. Figures 1-7 As shown, the processing equipment has been improved and optimized by adding a positioning unit 80. The positioning unit 80 is located on the discharge side of the feeding unit 20, and the feeding side of the feeding unit 20 is used for the initial placement of the workpiece 90. The positioning unit 80 includes a positioning frame 81, two positioning support plates 82, a baffle 84, a pressure sensor 85, and an elastic element 86. Furthermore, two side detection components 87 are added. The side detection components 87 include a side position detector 871, a side position trigger rod 872, and an elastic element 873. The side position detector 871 uses a pressure sensor from the prior art. The positioning frame 81 is mounted on the discharge side of the conveyor chain plate 21 and is located below the corresponding clamping unit 70. A positioning groove 83 is formed between the two positioning support plates 82. The inlet of the positioning groove 83 is connected to the outlet of the material passage gap 23. The workpiece 90 moves from the material passage gap 23 into the positioning groove 83 under the conveying action of the conveyor chain plate 21.

[0048] During operation, the workpiece 90 is first placed on the conveyor plate 211 and conveyed into the material passage gap 23 by the action of the conveyor chain plate 21 and the push rod 24. The steel back of the workpiece 90 is higher than the upper end face of the guide rod 22. The friction block part of the workpiece 90 (that is, the body part, which is generally composed of friction material, adhesive, etc.) is located in the material passage gap 23. The overall orientation of the workpiece 90 is adjusted by the two guide rods 22 until the workpiece 90 enters the positioning groove 83. At this time, the workpiece 90 separates from the conveyor plate 211. The steel back of the workpiece 90 overlaps with the two positioning support plates 82, and the friction block part of the workpiece 90 is located in the positioning groove 83 formed between the two positioning support plates 82. As the conveyor chain plate 21 continues to move and convey, under the pushing action of the push rod 24, the push rod 24 pushes the workpiece 90 to continue sliding along the positioning groove 83 and gradually approach the baffle 84 until the steel back of the workpiece 90 abuts against the baffle 84. A squeezing force is generated between the baffle 84 and the workpiece 90. When the baffle 84 presses against the elastic element 86, which is a spring from the prior art, the elastic element 86 transmits the pressure on the baffle 84 to the pressure sensor 85. After detecting the pressure, the pressure sensor 85 transmits the detection result to the controller in the form of an electrical signal. After receiving the transmitted electrical signal, the controller compares it with the preset limit value. If the detection result meets the requirements, it outputs an electrical signal indicating that the workpiece 90 is in place and outputs a control command to the servo motor to stop power output to the feeding unit 20, so that the feeding unit 20 stops conveying and the conveyor chain plate 21 stops moving the workpiece 90. At this time, the workpiece 90 in the positioning groove 83 is the next workpiece 90 to be fed. The designed positioning unit 80 can accurately determine whether the workpiece 90 has been conveyed to the correct position, improve the conveying accuracy of the workpiece 90, reduce the work loss caused by the workpiece 90 being missed, and thus ensure the saturation of the equipment, avoid the waste of equipment energy, and improve the stability of continuous operation of the equipment.

[0049] Meanwhile, when the workpiece 90 comes into contact with the baffle 84, the side trigger rod 872 on the positioning support plate 82 slides towards the friction block under the elastic action of the elastic element 873. The friction block is generally arc-shaped. The two side trigger rods 872 approach the inner and outer arc surfaces of the friction block respectively until they come into contact with the friction block. At this time, the two side detectors 871 detect two elastic forces respectively and transmit the detection results to the controller. After analysis by the controller, it is determined whether the two measurement results (the pressure between the friction block and the side trigger rod 872) meet the preset requirements. If the requirements are met, the controller outputs a signal that the workpiece 90 is facing correctly and simultaneously outputs an instruction to the clamping unit 70 to clamp the workpiece 90 normally. The workpiece 90 is clamped; if the inner and outer arc surfaces of the friction block are reversed during placement, the measurement result will be exactly the opposite of the preset requirement, that is, the workpiece orientation will have a rotation difference of 180 degrees. Before processing the workpiece 90, the controller will send a 180-degree rotation command to the clamping unit 70, and the orientation of the workpiece 90 will be adjusted by the rotation setting of the clamping frame 71; with the help of two symmetrically designed side detection components 87, the orientation of the workpiece 90 will be further confirmed based on whether the workpiece 90 has been delivered to the correct position. The output result detected by the side detection components 87 can effectively determine the orientation of the workpiece 90, thereby providing an accurate processing basis for subsequent processing, avoiding the failure of workpiece 90 processing due to reversed orientation, increasing raw material loss, and reducing product success rate.

[0050] If the model of workpiece 90 changes, the initial positions of the side detection component 87 and the baffle 84 can be adjusted appropriately to adapt to the operational requirements of different products.

[0051] In some examples, see, for instance. Figures 1-2As shown, the structures of the chamfering unit 30, the grooving unit 40, and the grinding unit 50 are detailed. The chamfering unit 30 includes a chamfering seat 31, a chamfering driver 32, and a chamfering disc 33. The grooving unit 40 includes a grooving frame 41, a grooving driver 42, and a grooving disc 43. The grinding unit 50 includes a grinding frame, a grinding driver 51, and a grinding disc 52. There are two grinding units 50. The first grinding unit 50 performs rough grinding and is located between the chamfering unit 30 and the grooving unit 40. The second grinding unit 50 performs fine grinding and is located between the grooving unit 40 and the feeding unit 20. During operation, when the clamping unit 70 above the feeding unit 20 removes the workpiece 90 (blank) from the feeding unit 20, each processing unit descends, and then the rotating frame 11 rotates at a preset angle, thereby gradually moving the workpiece 90 above the chamfering unit 30, the first grinding unit 50, the grooving unit 40, and the second grinding unit 50. Each processing unit then rises again to process multiple workpieces 90 simultaneously. After the current work cycle ends, each processing unit descends again, and the rotating frame 11 rotates at a preset angle again, so that all workpieces 90 gradually complete all processing operations.

[0052] The chamfering actuator 32 can be a motor from existing technology. The power output of the chamfering actuator 32 drives the chamfering disc 33 to rotate and perform chamfering and grinding on the corresponding workpiece 90. Using common linear transmission methods such as motors, lead screws, or hydraulic cylinders (existing technologies are not detailed here and are not fully shown in the figure), the chamfering seat 31 and the chamfering actuator 32 can be adjusted vertically, horizontally (towards or away from the rotating frame 11), and left and right. The appropriate method can be selected and matched according to actual needs. Combined with the rotational connection between the clamping frame 71 and the rotating frame 11, the clamping frame 71 can adjust the rotation angle of the workpiece 90 in real time, thereby adjusting the orientation of the workpiece 90 to meet the processing requirements of different types of workpieces 90. Preferably, there are two chamfering units 30, which are two adjacent processing units. By performing two chamfering operations, some complex chamfered surfaces can be processed in batches, effectively reducing the chamfering time per piece and improving overall work efficiency.

[0053] When the workpiece 90 is transferred to the first grinding unit 50 for rough grinding, the grinding disk 52 is rotated by the power provided by the grinding driver 51, and the grinding disk 52 begins to grind the exposed surface of the friction block; the grinding driver 51 is a motor in the prior art; similarly, the first grinding unit 50 uses common linear transmission methods such as motors, lead screws or hydraulic cylinders in the prior art (the prior art will not be described in detail, and is not fully shown in the figure) to adjust the up and down, front and back (closer or farther from the rotating frame 11) and left and right positions of the grinding frame and the grinding driver 51, and selects and matches according to actual needs. Combined with the rotational connection between the clamping frame 71 and the rotating frame 11, the clamping frame 71 can adjust the rotation angle in real time, thereby adjusting the orientation of the workpiece 90 to meet the rough grinding processing needs of different types of workpieces 90.

[0054] When the workpiece 90 is transferred to the top of the grooving unit 40, the grooving disk 43 is rotated by the power provided by the grooving driver 42, and the workpiece 90 on the clamping unit 70 is grooved. The grooving driver 42 is a motor in the prior art. Similarly, the grooving frame 41 and the grooving driver 42 are adjusted up and down, back and forth (closer to or away from the axis of the rotating frame 11) and left and right by using common linear transmission methods such as motors, lead screws or hydraulic cylinders in the prior art (the prior art will not be described in detail and is not fully shown in the figure). The selection and matching are made according to actual needs. Combined with the rotational connection between the clamping frame 71 and the rotating frame 11, the clamping frame 71 can adjust the rotation angle in real time, thereby adjusting the orientation of the workpiece 90 to meet the grooving processing requirements of different types of workpieces 90.

[0055] When the workpiece 90 is transferred to the second grinding unit 50 for fine grinding, similarly, using common linear transmission methods such as motors, lead screws, or hydraulic cylinders (existing technologies will not be elaborated further, and are not fully shown in the figure), the vertical, horizontal (near or far from the rotating frame 11) and horizontal positions of the grinding frame and grinding driver 51 are adjusted according to actual needs. After the grinding frame drives the workpiece 90 to the preset position, the rotating wheel 75 is aligned with the horizontally extending slide groove 54 on the stabilizer 53. Then the second grinding unit... The grinding driver 51 of the workpiece 90, under the combined action of a motor and a lead screw in the prior art, begins to move. The slide 54 gradually approaches the rotating wheel 75 until the rotating wheel 75 is completely inside the slide 54. At this time, the exposed surface of the workpiece 90 is finely ground with the power provided by the grinding driver 51. Combined with the design of the stabilizer 53, the slide 54 and the roller, the vibration of the workpiece 90 during grinding can be effectively reduced, the stability of the workpiece 90 is improved, and the fine grinding effect is improved. The occurrence of rework, grinding failure and other phenomena is reduced, and the overall processing efficiency is improved.

[0056] After the fine grinding is completed, the corresponding grinding driver 51 continues to slide to the rotary wheel 75 to separate from the slide groove 54. Then, with the help of the robotic arm (not shown in the figure) set on one side of the base frame 10, the robotic arm can be a multi-axis robotic arm commonly used in the prior art, or a simple telescopic arm that makes linear motion, etc. The robotic arm is a prior art and will not be described in detail here. The robotic arm moves to the bottom of the clamping unit 70, and the two clamping members 72 release the clamped workpiece 90. The workpiece 90 falls onto the robotic arm and is then transferred to the next operation. Throughout the processing, dust collection hoods with upward openings are set at the corresponding positions of chamfering, grooving and grinding operations. The dust collection hoods are connected to the dust collector in the prior art through the dust collection pipe. The dust collector removes the dust and debris generated during the processing of the workpiece 90 with the dust removal capacity, purifying the working environment and reducing environmental pollution.
